Meteorological Factors Leading up to the Flood of 2008
The culmination of many above normal to record meteorological factors, from the winter of 2007-2008 through the spring of 2008, led to the historic Midwest Flood of June 2008. Locally this flood might be most remembered for its devastating impacts in the Cedar Rapids, Iowa City, Oakville, and Gulfport areas.
